Mateo Caballero

My passion, legal skill, and commitment to justice stem from years of work in both the private and non-profit sectors. My primary practice is civil rights and liberties both against the government and employers. If you have been discriminated against, harassed at work, or your liberties have been violated, I want to hear from you. At my firm, we believe in making justice work for our clients through efficient, personalized, and outstanding legal services.
